BUTTON-MAKING MACHINE.

Specification of Letters Patent,

Patented Dec. 25, 1906.

Application led June 1'7, 1905. Serial No. 265.636.

T0 all whom. it may concerm Be it known that we, HARRY B. EMBLER andELBERT D. WV. ROSE, citizens of the United States, residing at ARoseton,in the county of Orange and State of New York, have invented certain newand useful lmproveniente in Button-Making Machines, of which thefollowing is a specification, such as will enable those skilled in theart to which it appertains to make and use the same.

T heobject of this invention is to provide a machine for manufacturingbuttons of pearl, ivory, bone, and the like from suitable blanks, saidmachine being adapted to engage and hold said blanks during the processof forming them into buttons and also during the process of drillingholes therethrough, a further object being to provide a machine of thisclass whereby a pluralityT of buttonblanks may be engaged and carried toa position for forming and when in said position be rapidly rotated andduring said rotation be cut to the desired shape and size and after saidoperation of forming to be carried to a position for drilling, in whichposition a plurality of regularly-spaced thread-holes may beautomatically drilled therethrough, a still further object being toprovide a machine of this class wherein the cutting and drilling devicesare operated only when the blanks are in position for'being operatedupon and which also automatically releases said buttons when formed anddrilled, thereby being in position for the insertion of other blanks,and also to provide a machine of the class hereinafter described andclaimed which is comparatively simple in construction and operation andwell adapted for the purpose for which it is intended.

The invention is fully disclosed in the following specilication, ofwhich the accompanying drawings form a part, in which the separate partsof our improvement are designated by suitable reference characters ineach of the views, and in which- Figure l is a plan view of abutton-making machine constructed according to our invention; Fig, 2, aside elevation thereof; Fig. 3, a longitudinal vertical section on theline 3 3 of Fig. 2 3 Fig. 4, a transverse vertical section on the line a4 of Fig. 8; Fig. 5, a horizontal section on the line 5 5 of Fig. 3;Fig. 6, a partial section on the line 6 G of Fig. Fig. 7, a partialsection on the line 7 7 of Fig. 5, and

' said Fig. 8 a detail view of one of the parts of our machine.

In the drawings formin part of this speci- {ication we have shown a asea, comprlsln longitudinally-arranged side members a2 an transverse endmembers a3, and arranged centrally of the side members 01,2 are supportsa4, adapted to receive a shaft b, which 1s rotatably mounted therein.

Arranged centrally and longitudinally in the base a is a shaft c, whichcarries two carndisks c2 and c3 within the base a, and a earwheel ciL atthe rearward end of said ase,

gear-wheel meshing with a similar gearwheel' c5, secured to a shaft c,rotatably mounted in a frame or support d, secured to the top of thebase a at the rearward end thereof, and the gear-wheels c4 and c5 are ofthe same dimension and have the same number of teeth, and it will beseen from this construction that the rotation of the shaft c rotates theshaft 0G correspondingly.

As shown in Fig. 1, the frame or support d is provided with abevel-edged recess (Z2, in

which is slidably mounted a vertically-movable plate (Z3, and the plated3 is provided with a bevel-edged projection, the beveled edges of whichare horizontally arranged or at right angles to the bevel edges in thesupport d, and slidably mounted on the beveledged projection d* is acarrier d5, provided witha substantially square opening d in the centerthereof, and slidably mounted on the carrier d5 is a frame e, which isprovided with a downwardly-directed headed bolt e', engagedby the grooveof the cam-disk c3 and slidable in a slot d? of the carrier d5, and thegroove of the cam-disk c3 is provided with four offsets', thereby movingthe frame e longitudinally of the base a in one rotation of the shaft c.

Secured to the shaft c and operating within the square opening d of thecarrier d5 is a disk d8, which is provided with an offset (Z9 on oneedge of its periphery, and as will be seen from the construction alreadydescribed the carrier d5 is vertically and horizontally movable, andsaid movement is accomplished by means of the oil'set d striking againstthe inner surfaces of the opening d in said carrier, said offset movingthecarrier to the right or left or upwardly in either of its right orleft positions and downwardly in either of its right or left positions,thereby produc- IOO ing a movement of the carrier d5 corresponding to anequal lateral parallelogram, and it will also be seen that one rotationof the shaft c moves the carrier (Z5 into its four positive positions.

The frame e carries at its top a plurality of rotatable shafts e2, toeach of which is secured a pulley eafa'nd to the outer or forward endsof the shafts e2 are'secured chucks e4, in each of which is firmly helda drill e5, and the pulleys e3 are adapted -to be operated by a belt e",connected with any suitable part of the machine or exteriorly in orderthat all may be moved in unison, and when the shaft -c is rotatedthrough one revolution it will be seen that the drills e5 arecarriedforwardly and backwardly four times, each of said forward andbackward movements being accornplished in one of the four positions ofthe carrier d5.

Mounted on the base a, at the end opposite to the drill-frame e, is aslide f which is operated longitudinally of the base a by means of the-groove in the cam-disk c2, in which a headed bolt f2 of the slide foperates, this backward-and-forward movement being accomplished onceonly during a complete rotation of the shaft c, and movable transverselyof and on the slide f are a plurality of plates f3, each of which isadapted to be adjusted by means of screws f 4, one of which is providedfor each ofsaid plates f3, as is clearly shown in Fig. ,1, and each ofsaid plates is also provided with a screw-threadedlongitudinally-arranged rod f5, which is normally forced-forwardly bymeans of a spring f 6, mounted in the -plate f3, and the screwthreadedend of the bolt f5 engages a frame g, in which is mounted avertically-movable member g2, adapted to be movable'vertically by meansof a screw-threaded bolt g3, and

the member q2 carries at its top a blade or cutter g4, adjustablymounted therein and secured thereto by means of thumb-screws g5, and bymeans of this' construction it will be seen that the member g2 of theframe gis vertically adjustable and lthe frame g is longitu-y dinallyadjustable on the plate f3 and the `plate f3 is transversely adjustableon the slide f, and said slide f is adapted to be moved longitudinallyby means of the camdisk c2.

Rotatably mounted in one of the supports a4 is a shaft h, provided withaWorm gearwheel h2, which is adapted to be rotated by means of a Worm h3,arranged on a shaft h4, mounted outside of the base a, and the shaft 7L*is provided with a pinion h5 at its outer end, said pinion beingenmeshed with a gearwheel h", mounted on a shaft k7, which also carriesa pinion ha, which is enmeshed with the gear-wheel c4, all of which isdiagrammatically shown in Fig. 4, and connected'.

with either the shaft h7 or the shaft h4 are pulleys h, with which theusual belt may be connected for operating the same, and when saidpulleys are rotated inthe operation of the machine it will be seen thatthe shafts c,

' c, h4, and k7 are rotated correspondingly.

Secured to the shaft h, within the support a, is a cam-disk i, providedWith an offset 'i2 in its periphery, and the disk i is also providedwith a cam-groove i3, as is clearly shown in Figs. 3 and 8, and anantiriction-roller i, mounted on an arm i5, secured to the shaft l),operates in the cam-groove rBof the-disk i, and when the shaft h4 isoperated the shaft h is also operated, the ratio of said rotation beingfour rotations of the shaft h4 to one rotation of the shaft h, and theshaft h is also provided with a wheel t", which carries a segment-gearTon its periphery, and said segment-gear is rotated at the same speed asthe cam-disk fi.

Rotatably mounted on the shaft b is an annular casing 7c, which isprovided with a pinion k2 at the end adjacent to the segmentgear t7, andsaid segment-gear is adapted to operate said pinion k2, and thereby saidcasing le, said operation occurringv .intermittently and through apredetermined arc of a circle, said arc being preferably, .in the formof construction shown, ninety degrees of a circle, Aand in Fig. 1 wehave shown a lock in engagement with the casing k for holding thesame"in any of its four positions, said lock comprising aspring-operated plunger m, with which is connected a toggle-levermvwhich projects over the cam-disk i and bears thereon, and when-theoset i2 of the cam-disk 'i reaches the toggle-lever m2 said lever 4isoper- ICP- ated and the plunger in is forced outwardly and out ofengagement with the casing c, and

said casingis free to be rotated, and from the relation of thesegment-gear L7 to the offset t2, as clearly shown in Fig. 3, it will beseen that the plunger m is withdrawn just before the segment-gear ilreaches-the pinion k2, and

lbeing accomplished independently of the shaft b and independently ofthe casing 7c, as will be readily seen, and secured to the sleeve n andoperating in a recess k3 of the casingk is a bevel gear-Wheel n2, whichin the operation of our machine is continually in motion, and secured tothe base a, outside of but adjacent to the bevel gear-wheel n2, is aninternal cam n3, provided with an oset n* at one point thereof, .saidpoint lbeing preferablyvon the horizontal plane of the shaft b, forreasons hereinafter described, and pivotally connected with the casing7c at predetermined points are levers ns, which carry rollers n at IIStheir outer ends, there being four of the levers '71,5 and rollers n, asshown in Fig. 7, and the `rollers n operate in the cam-disk n3, as isclearly shown in said figure.

Secured to the shaft b, within the casing 7c and at each side thereof,are two internal camdisks 0, which are similar to each other, and thesecam-disks are adapted to be operated by the shaft b, and said shaft b isoscillated, as previously described, by means of the arms i5, securedthereto, and thecam-groove i3 in the cani-disk i, and, as shown in Fig.7 four transversely-arranged bars o2 extend between and into the cams 0and are operated thereby, and the cams o are provided, as shown in Fig.7, with a portion o3 of a smaller radius than that of the balance ofsaid cam, and the bars o2 are adapted to be curved inwardly andoutwardly in the oscillation of said cam-disk o.

Arranged in suitable supports in the casing k and in predeterminedpositions are a plurality of blank-holders p, which, as shown in thedrawings, are four in number in each of the four positions thereof, andeach of said holders comprises a tube p2, provided with a cap p3 at itsinner end and being open at its outer end, and secured in the cap p3 isa sleeve p4, mounted on a rod p5, which is provided adjacent to itsouter end with a pin p, which passes through slots in the sleeve p4 andinto a tube p7, which is provided with an inwardly-beveled o ening atits outer end, and secured in the s eeve p4 at its outer end is a headr, which is provided with an inclined or cone-shaped neck portion r2 andwith a disk 73, and the head r is slotted, as shown at r, in oppositedirections, thereby quartering the disk 1*?, as well as most of the headr, thereby permitting an inward and outward movement of each of the foursections of the disk r3lso obtained, and the disk 13 is also providedwith a recess r4, which is adapted to receive one of the button-blanks,and the inner ends of all of the rods p5 'are rotatably`mounted in thetransversely-arranged bars o2, and when said bars o2 are moved by meansof the camdisks o the tubes p7 are moved against the operation ofcoil-spring p8, and the inward movement of the tubes p" permit theoutward movement of the four members of the head r, and the outwardmovement of the tubes p7, operating on the beveled neck member of thehead r, forces the members thereof inwardly, and thereby firmly holdsthe blanks contained in the recess r4, and each set of four holders areconnected with a corresponding one of the transverse bars o2 and are oerated by the said bars in unison. Loose y mounted on each holder ofeach of said sets of holders adjacent to the gear-wheel n2 is albevel-gear s, which is always in rotation durlng the operation of ourmachine, and 'secured to each of said holders is a ear-wheel s2, asshown in Fig. 6, by means of ee wheels s3, rotatably mounted in thecasing le, and the gear-wheels s2 are thereby rotated at the same speedand in the same direction, and keyed to suitable collars on thegear-wheels s2 of the holders upon which the bevel-gears s rotate areclutches s4, which are normally forced inwardly by means of strongcoilsprings s5 into engagement with the bevelgears s, and the clutchess* are adapted to be moved backwardly by means of the levers 1145, whichare in engagement therewith, said levers being operated by means of thecam n3, and it will be seen from this construction that when the ciutchS4 engages the corresponding bevel-gear 's all of that set of holders pare rotated; but because of the position of the offset n4 of the cam m3said rotation of the holders p occurs only when the heads r of each ofsaid sets are in line with and adjacent to the cutter-blades g4, andwhen the roller n of the lever ns is again forced inwardly the clutch s4is released from the bevel-gear s and the rotation of the holders p ofthat particular set ceases.

'In Fig. 2 of the drawings we have shown atable t, mounted on suitablesupports t2, se- ,cured to the supports a, and theinnenedge of the saidtable is adjacent to the vertical plane of the shaft I), and said tableis adapted to hold the button-blanks which are adapted to be removedtherefrom into the heads r of the holders p manually, this operationbeing performed when the casing It' is in one of its locked positions,at which time the heads of the set of holders arranged vertically abovethe shaft I) are in their distended positions, because of the fact thatthe corresponding bar o2 is drawn inwardly by the offset o3 of the camso, and the heads of the set of holders arran ed horizontally and to theright of the shaft are closed, because of the fact that thecorresponding bar o2 is in its outward position, and just previous tothe unlocking of the casing k and its rotation through an arc of ninetydegrees from its position the shaft b is o erated by means of the arrni5, as previously described, and the cams 0 are oscillated in thedirect-ion of the arrow fr, as shown in Fi 7, at which time the bar o2of the set of ho ders last described is drawn inwardly, and therebydistending of the jaw of the holders of said set and permitting thebuttons to drop out, and the bar 02 of the vertically-arranged set ispermitted to be forced outwardly after having passed the offset o3 bymeans of the coil-springs ps, andthe laws of the holder-heads arecontracted thereby and firmly grasp the blanks at the same instant thatthe finished buttons are being dropped out the horizontally-arranged setof holders, after which the said set of holders are carried through anarc of ninety degrees, and the casing 7c 1s again locked in position.When the blanks just described as having been fed into the holders ofthe vertically- IOO ITO

arranged holders reach a position adjacent to the cutter-blades g4, thecasing k is locked, the cam c2 moves the slide f forwardly, and therebythe cutter-blades g4 against the said blanks, the clutch s4 en ages thebevel-gear s of this set, and the ho ders of said set are rapidlyrotated, after which the slide f is moved backwardly, and the casing lcis again unlocked and rotated through anl arc of ninety degrees, atwhich time the formed blanks are arran ed beneath the shaft b, and a newset of blans having been fed into the successive set of 'holders said.blanks have been carried to a position adjacent to the cutter-blades g4,and the second set of blanks is formed and a new set of blanks is fedinto the second successive set of holders, after which the casing 7c isagain rotated throu h an arc of ninety degrees, whichbr'ings t e firstset of formed blanks to a position adj acent to the drills e5. 'Y

When the casing 7c has been locked in the position just described, thecam c3 moves the drill-frame e forwardly, and as the shafts e2 thereinare continually rotated by means of the belt e6 or by any other suitablemeans the drills e5 are forced into vthe formed or turned blanks and arewithdrawn therefrom, at which time the carrier d5 is moved into all ofits four positions, and the'drills e5 are again forced throu h theformed blanks, and this forward an -backward movement of the vdrills e5through the formed blanks is` accomplished in each of the our positionsof the carrier d5, thereby drilling four holes in each of the formedblanks, and thereby nishing the buttons, and just aften the drillingrotation of the carrier di* the said inished buttons are released fromthe heads of the holders and are dropped therefrom into any suitablereceptacle or chute.

In Fig. 3 of the drawings we have shown an automatic blank feedingmechanism which is arranged directly over the upwardlyVvertically-arranged set of holders and comprises a cylindricalreceptacle u, in which the blanks are placed, and rotatable in an arm`u2, secured to the receptacle u, is a cam-disk 11,3, which opeijates aslide 11,4, arran ed b1- neath the receptacle u, and arranged irectlyover the head 1* of the holders is a spring-operated vertically-movableplunger '115, which is moved upwardly by means of the arm u,

which carries an antifriction-roller 11,7, whichis operated by thecam-disk ug, and when the said cam-disk is rotated the slide a4 is drawn1 backwardly, thereby permitting the blanks to drop, and inthe forwardmovement of the slide u, occasioned by means of the coilspring u8,onevof the blanks is carried t'o a position over the head 1' of theholders, which are at this time in their distended positions, at whichtime the plunger 11,5 descends and forces the said blanks into therecess T4 of the head 7', after which time the jaws of the head 1' arecontracted, thereby grasping the blanks, and the members of the feedingmechanism assume their normal position, and this operation is adapted tobe repeated as often as a new set of holders reach a position adjacentto the said feeding mechanism; but it will be understood that any othersuitable feeding mechanism may be employed for -this purose. p By meansof this description it will be seen that a set of button-blanks areadapted to be engaged by one of a plurality of sets of holdder, and saidbutton-blanks afterbeing irmly locked in said holders are carried to aredetermined osition, where they are rapidly rotated, an at the sametime a corresponding -ers arranged on a rotatably-mounted cylinnumber ofcutter-blades are forced against the said blanks,and after the saidblanks are formed the cutter-blades are withdrawn and the casing iscarried through a predetermined4 arc of a circle and again locked, afterwhich said formed blanks are carried to aA position adjacent to adrilling mechanism, where a redetermined number of holes are drilled terethrouo'li, after which the said finished blanks or zbuttons arereleased from said holders and are removed from said inav,chine in anysuitable manner, and this operation is repeated as often as desired witheach set of blank-holders employed in said casing While we have shownbut four sets of blank-holders arranged in our machine, it will beapparent that any number of sets may be employed andk any number ofholders in each of said sets may be employed, and various means foractuating the casing, the cutterblades, or the drilling mechanism may beemployed, and various other changes in and modifications of theconstruction herein shown and described may be made without departingfrom the spirit of our invention or sacrificing its advantages. v j
